The term "serious" in literature often conveys a range of nuanced meanings, from a solemn demeanor to the gravity of a situation or emotion. In some works, it marks a character’s intent or mood, as when a character displays a “serious air” that sets the tone for an important life event [1] or assumes a careful, reflective disposition [2]. Other writers use it to underscore the weight of a circumstance—whether the significant consequences of an action are emphasized, as in discussions of severe outcomes [3, 4], or the earnestness in emotional or intellectual engagements is highlighted [5, 6]. At times, the term even acquires a conversational quality, serving to question or confirm the level of intent behind remarks [7, 8]. Overall, “serious” operates as a versatile modifier that enriches narrative tone and deepens character insight.
